The quadrupole coupling constants, asymmetry parameters and spin-lattice relaxation time of27A1 nuclei have been studied in Mn-doped YAlO3 crystals. The dependence of the relaxation time on temperature and concentration of Mn ions implies a mechanism of relaxation via Mn2+ paramagnetic ions taking into account the nuclear spin diffusion partly restricted by the diffusion barrier. A substantial increase of the relaxation times was observed in the photoexposed samples. We ascribe this effect to the appearance of fast-relaxing Mn5+ ions produced by photoionization of Mn4+ centers.
